Magnesium Oxide Product Overview
Magnesium oxide (MgO), chemically known as MgO, is a white, loose, powdery inorganic compound. It is an ionic compound with a high melting point (2800°C) and a high boiling point (3600°C). It is insoluble in water at room temperature, with a water solubility of 6.2 mg/L at 20°C. It has a moderate density of 3.58 g/cm³ at 25°C and a molecular weight of 40.30. Magnesium oxide is generally classified as light or heavy magnesium oxide, each with different properties and uses depending on its processing method and application.
